The old phrase “if it isn’t broke, don’t fix it” definitely rings true for Cindy Crawford‘s go-to workout moves. The model has been doing the same routine for 30 years—and it’s just as effective now as it was then.

“I do anywhere from 30 minutes to an hour of old-school lunges, weights, squats, and bicep curls—it’s just stuff that I learned 30 years ago.” —Cindy Crawford

“I try to get 20 minutes of cardio at least three times a week. Then I do anywhere from 30 minutes to an hour of old-school lunges, weights, squats, and bicep curls—it’s just stuff that I learned 30 years ago,” she told The Cut. “Sometimes the cardio is jumping on a trampoline, using a treadmill or elliptical, or running.”

And, being the busy #bossbabe she is, Crawford is also a huge fan of multitasking while she’s toning.

“I put on an audiobook or music while I run the stairs at my house for 20 minutes. I just finished the Amy Schumer one, which was fantastic,” Crawford said, adding that she also tries to take a weekly hike with a girlfriend to catch up—while clocking in steps.

Basically, Crawford is proof that exercising doesn’t need to be complicated. Whether you want to bounce on a trampoline it up or hit the trails with your bestie, you’re sure to get your heart rate up—and share some laughs in the process.
